CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 415,295, dated November19, 1889.

Application filed August 9, 1889. Serial No. 320,237. (No model.)

To all whom t may concern:

Be it known that I, ITHAMER M. JONES, a citizen of the United States,residing at Elm Mott, in the county of McLennan and State of Texas, haveinvented certain new and useful Improvements in Car-Couplings; and I dohereby declare the following to bea full, clear, and exact descriptionof the invention, such as will enable ot-hers skilled in the art towhich it-appertains to make and use the same.

This invention relates to car-couplings; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed.

In the drawings, Figure is a plan view from above, partly in section,lof the two halves ot the coupling ready to be pushed together. Fig. 2is a side view of the saine.

A is a coupling-head provided with a stein a for attaching it to thecar, and B is a coupling-socket, also provided with a stem a forattaching it to the reverse end of anothercar. The coupling-head A isprovided with a central projecting tongue C at its front end, having theshoulders c for the front edges b of the socket B to strike against.

I) are pockets formed in the coupling-head upon each side of the centraltongue, and E are hooks having their rear ends e abutting against thebottoms of the said pockets. The pockets are wider than the ends c ofthe hooks, so that the hooks are free to move laterally, and F arepivot-pins, which retain t-he ends of the said hooks in the pockets. Thefront edges f of the pockets are beveled, and g are correspondinglybeveled shoulders on the hooks, which permit the ends of the hooks to beforced inwardly toward the central tongue and prevent the hooks frombeing forced too far in the opposite direction.

II are springs secured by rivets 7L to th central tongue, and havingtheir free ends bearing against the hooks and pressing them outwardly.Shoulders are formed upon the hooks E substantially in line with t-heshouldersc on the central tongue and for the same purpose.

I is a vertical spindle journaled in the central tongue, and j areiiexible cords or chains wound upon the spindle and secured to it at oneend and having their opposite ends secured to the hooks E. The verticalspindle may be revolved to wind up the chains and draw the hooks inwardby means of any convenient forni of handle applied to the top of it.

The coupling-socket is provided with a cavity J and 7c are holes in thesides, which leave the catches m in the front of the couplingsocket forthe hooks of the coupling-head to engagewith. When the cars are pushedtogether, the beveled edges m on the front of the hooks strike againstthe catches m on the socket and the hooks are pressed inward, enteringthe cavity and springing outward through the holes k as soon as theirhooked front ends have passed the catches. The springs II keep the twohalves of the coupling coupled together, and the shoulders c and t'prevent the front ends ofthe tongue and the hooks from striking againstthe bottom of the cavity J. The coupling-head is uncoupled from thesocket by revolving the spindle I and winding up the chains or cords, soas to draw together the hooks until they clear the catches onthe'socket.

Vhat I claim is- 1. In a car-coupling, the combination, with thecoupling-head provided with a central tongue having shoulders c, and thespringactuated hooks pivoted to said head on each side of the tongue andprovided with shoulders z', of the coupling-socket provided with acavity having catches m at its sides for the said hooks to engage with,substantially as and for the purpose set forth.

2. In a car-coupling, the combination, with the coupling -head providedwith a central tongue and a socket on each side of the tongue, andtheforwardly-projecting spring-actuated hooks pivoted to the said head,with their rear ends abutting against the bottoms of the sockets andprovided with beveled front edges fm', of the couplingsocket providedwith catches m for the said hooks to engage with automatically, and thevertical spindle journaled in the central tongue and provided withiieXible connections wound upon it and secured to the hooks for drawingsaid hooks inwardly, substantially as set forth.

3. In a car-coupling, the combination, with IOO the coupling-headprovided with a central catches for the said hooks to engage withautongue, andl pockets on each side of the tongue tomatieally,substantially as set forth. 1o having forwardly and outwardly projectingIn testimony whereof I affix my signature in beveled edges f, and thespring-actuated hooks presence of two witnesses.

provided with ends pivoted in said pockets I. M. JONES. andwith beveledshoulders g corresponding Vitn-esses: With said edges f, which limittheir' Outward T. C. GABRIEL,
